I'll be adding your Tested-by and I'll keep you cc'd on the series. It'll
look a little different because I'm expect to adjust it slightly to match
Andrew's tree but there should be no major surprises and my expectation is
that testing a -rc kernel after it gets merged is all that is necessary. I'm
planning to backport this to -stable but it'll remain to be seen if I can
convince the relevant maintainers that it should be merged.
